Design of Road Surface Lighting System for Rear Lamp using Automotive Ultrasonic Sensor

摘要

There are quite a lot of accidents with pedestrians when backing a car. To prevent such accidents, recently, road surface lighting has appeared in the automotive industry. This technology is used to inform pedestrians that the vehicle is approaching by projecting light onto the road surface. In this paper, we propose the technology that changes a light pattern according to pedestrian's position to improve his visibility by linking existing automotive ultrasonic sensors and road surface lighting module.
